摘要:
A method for the recycle treatment of nickel plating waste water, in order to efficiently recover the nickel components from waste water which has been used for the washing of nickel plated products in a form re-usable as a nickel plating solution as such, wherein the nickel plating waste water is mixed with an aqueous alkaline component so as to remove, by precipitation in the form of hydroxides, contaminating metal ions other than nickel; the filtrate so obtained is treated through an ion exchange process so as to obtain an aqueous solution of nickel salts containing excess free sulfuric acid, a portion of which is then treated with alkali so as to precipitate nickel hydroxide which is separated in the form of nickel hydroxide through filtration by means of a centrifuge; the nickel hydroxide so obtained is then added to the rest of the aqueous nickel salt solution for neutralization with the free sulfuric acid contained therein to form nickel sulfate; and the free sulfuric acid is then removed so as to obtain a highly concentrated nickel sulfate solution.

A starter relay structure for a vehicle, where an electronic control unit of the vehicle controls the starter relay structure. The starter relay structure comprises a first relay and a second relay activated by an ignition signal from the electronic control unit. The starter relay structure further include a third relay activated by an output of the second relay, where an output of the first relay is provided as an input to the third relay.

An ultrasonic emission device is accommodated in a housing for generating an ultrasonic wave. The housing has an ultrasonic emission port for emitting the ultrasonic wave from the ultrasonic emission device outward therethrough. A louver is equipped to the ultrasonic emission port. The louver includes multiple louver boards, which are distant from each other. Two of the multiple louver boards adjacent to each other form a clearance therebetween. The clearance includes a horizontal clearance extending along a horizontal direction and an inclined clearance being an ascent inclination toward the ultrasonic emission device.

An engine for a snow vehicle has a crank shaft supported by a crank case along the width direction of the snow vehicle. An oil pan is disposed below the crank case. A cylinder block is disposed above the crank case. The engine is mounted on the snow vehicle such that an axis of the cylinder block is inclined rearward. An oil pump is disposed behind and below the crank shaft. An oil filter is disposed in front of the crank shaft.

An RFID tag formed on an original includes a storage unit which stores data representing, e.g., the number of times of scan of the original and the generation from a parent original, and a transmitter/receiver which transmits and receives the data by radio. A read/write circuit receives data from an RFID tag of an original by radio. On the basis of the received data, read of the original is controlled. While the original is being read, the received data is edited in accordance with the control. The read/write circuit transmits and writes the edited data in the RFID tag.
摘要:
A dry etching method by which a substrate can be dry-etched on both sides without a crack is provided.The dry etching method includes: introducing an etching gas having a fluorocarbon gas and a rare gas into a vacuum chamber; generating plasma in the vacuum chamber having a predetermined pressure; and etching a substrate to be processed adhered on an adhesive surface of a heat-conductive sheet disposed on a substrate table.

In the fine processing of holes and/or trenches by dry-etching an interlayer dielectric film covered with a resist mask formed by ArF-photolithography within a plasma atmosphere, the etching gas used comprises a halogen atom-containing gas (the halogen atom being selected from F, I and/or Br) or a fluorinated carbon atom-containing compound gas in which the ratio of at least one of I and Br is not more than 26% of the total amount of the halogen atoms as expressed in terms of the atomic compositional ratio and the balance of the gas consists of fluorine atoms. Occurrence of striation can be suppressed and a high processing accuracy through etching can be accomplished.
摘要:
A housing has an intake passage extending substantially in a vertical direction of a vehicle. A valve is configured to open and close the intake passage. A shaft supports the valve. A bearing supports the shaft. A hose is connected with an upper side of the housing in the vertical direction and configured to lead intake air into the intake passage. A communication passage configured to communicate an inside of an internal combustion engine of the vehicle with the hose. The communication passage has an opening in the vicinity of a point directly above the bearing. The hose has a wall surface defining a condensate passage, which connects the opening with a target location from which condensate is to be dropped.

The present invention provides a plant-activating agent for improving the activity of plants efficiently without a chemical injury onto the plant. The plant-activating agent is selected from the group consisting of (1) an organic acid derivative which is derived from the organic acid having two functional groups and wherein at least one of the above-mentioned functional groups is bonded to a group containing 1 to 30 carbon atoms; (2) a compound represented by the formula (II): RCOO(AO)nX1 (II) wherein R represents an alkyl or alkenyl group having 11 to 29 carbon atoms; X1 represents a hydrogen atom, an alkyl or acyl group having 1 to 30 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, or a counter ion; AO represents at least one group selected from oxyethylene, oxyprolylene and oxybutylene groups and may be random or block; and n represents an average number of moles added and is zero to 30; and (3) a glycerol derivative. If necessary, the agent is used together with a surfactant, a fertilizer component or a chelating agent.
